make.cbase: make.cbase

In HumanExposure/SHEDSDevel: The SHEDS-HT model for estimating human exposure to chemicals.

Description

Extends the base data set, output from the generate.person.vars function, to include a set of chemical-specific exposure variables. Currently, all new variables are initialized to zero.

Usage

make.cbase(base, chem)

Arguments

base	Data set of all chemical-independent information needed for the exposure assessment. Each row corresponds to a simulated person. The variables consist of age, gender, weight, diet and activity diaries, food consumption, minutes in each micro, and the evaluation of the exposure factors for that person.
chem	List of the chemical(s) of interest, determined via the chemical input in the Run file. The exposure variables for the specified chemicals will be appended to the base data set.

Value

The output is a data set cb consisting of the base data set, appended by the following columns:

chemrep

The unique ID corresponding to each chemical specified in the chem argument.

inhal.abs.f

For each person, the fraction of absorption of a given chemical when inhaled.

urine.f

For each person, the fraction of intake of a given chemical that is excreted through urine.

exp.inhal.tot

For each person, the total exposure of a given chemical via the direct inhalation scenario.

dose.inhal.tot

For each person, the corresponding dose for total exposure of a given chemical via the direct inhalation scenario.

exp.dermal.tot

For each person, the total exposure of a given chemical via the direct dermal application scenario.

exp.ingest.tot

For each person, the total exposure of a given chemical via the direct ingestion scenario.

exp.dietary.tot

For each person, the total exposure of a given chemical via the dietary scenario.

exp.migrat.tot

For each person, the total exposure of a given chemical via the migration scenario.

exp.nondiet.tot

For each person, the total exposure of a given chemical via the non-dietary food exposure scenario.

exp.ddd.tot

For each person, the total exposure of a given chemical via the down the drain scenario.

exp.window.tot

For each person, the total exposure of a given chemical via the out the window scenario.
